The 20-year-old put on quite a show Saturday during Israeli electronica DJ Borgore's "Christmas Creampies" concert at the Fonda Theatre in Hollywood. Appearing as a surprise guest performer, Liam Hemsworth's fiancée hit the stage after midnight and showed some serious skin while singing and dancing with a topless stripper.

For her performance, Cyrus emerged wearing body-hugging black stretch pants and a chest-exposing crop top that left little to the imagination. The former "Hannah Montana" star also had on a chain belt that doubled as a necklace and knee-high python boots.

The tattooed Cyrus clearly had some fun with the audience. She strutted around the stage alongside a topless pole dancer, who was outfitted in just a thong and pasties. (Surely Cyrus knew it would draw comparisons to her controversial performance on a stripper pole at the 2009 Teen Choice Awards.) She also got cozy with Borgore — dancing up against him on stage.

Cyrus also showed off an even shorter 'do. After debuting her edgy new hairstyle in August, she's since chopped off the floppy bangs she initially had. Now it's buzzed all over in a Mia-Farrow-pixie-meets-punk-rock style.

Cyrus is all about her upcoming fourth studio album. Although she became engaged to Hemsworth last spring, she recently said on "The Ellen DeGeneres Show" that the wedding will take place down the line as her current focus is her album and upcoming tour. "I'm, like, so focused on my record," Miley told DeGeneres. "I kind of don't want to be in between touring and trying to plan all that."

While we will have to wait until 2013 to see what she has in store musically — the album will feature a collaboration with Pharrell Williams — Cyrus recently worked with Borgore on his club tune, "Decisions." The video features porn star Jessie Andrews, as well as a unicorn, a goat, and a woman who smashes watermelons with her breasts.

So we suspect her new album will be a lot like Saturday's show — amplified.
